Research On Strategy For Validity Judgment Of Individuation Joint Motion Parameters

In motion capture system, the correctness of joint motion parameters computed by gathered data is a focus of researchers. Analyses various existing methods for judging the validity of motion parameters, including rigid body relation, reachable spatial scope, the limit range of joint angle based on statistics, motion smoothness degree etc., and then brings forward a new strategy for validity judgment --- a strategy with individuation and association of each performer. By creating and saving the limit space of each joint, translates the validity problem into space geometry problem, decreases the algorithmic complexity degree by special partition, and finally shows an exemplification for it.
